Looking for a good USB-based video capture device
The capture card I have in this computer is a complete piece of trash that can't do anything right.
I have been looking for a device that can capture from component for ages, but I only found two, a PCI-E card that costs $350 from a company called Black Magic, and a $250 or so standalone device meant to stream HD sources from one place of the house to another, but apparently had a built in HDD to record too that I saw at Frys. So for the time being, until more options are available (and I build a desktop with hardware designed in this century so it can actually handle a PCI-E card.... or HD video period) I am going to have to make do with SD video. Now....... my desktop still sucks, but my laptop is decent at least. Which is why I am looking for a USB based device that can capture video from composite. I know there are several out there, but I have no idea which ones are any good, and what, if any, features they support. This is why I am asking for recommendations. Can anybody recommend for me a good video capture device that can capture video from composite and connect to a PC by USB? Preferably something under $100 if possible, I don't have a lot on me right now. I will probably be capturing in RAW for the purpose of keeping the CPU free so there will be no framedrops and then encode it with a codec (likely Xvid or h264) after the capture process is complete.

Canopus makes really good capture cards (ADVC-100, -50 and -300, here in Europe) but they are DV (FireWire).
Normally I do not recommend capture cards since they are "economy class" and they are placed within the EM storm of the PC. External USB cards are no much better, but for constructive reasons ... And about capturing RAW, well, hmm, I'm not sure your HDD will keep up, especially a laptop one. Use a lossless (Huffyuv) or M-JPEG. Last edited by Ghitulescu; 9th June 2009 at 14:56. |

@Ghitulescu
Well.. Here's something you might call an economy class capture card (PDI Deluxe/SweetSpot) inside a PC Vs. Canopus ADVC-300. Canopus is about 3x as expensive. Left PDI / Right Canopus (histogram(mode="luma")) http://www.siluriformes.net/mm/pdi-canopus.png PDI gives interference free picture, the noise is at the source. I wouldn't rule Canopus out, but it's not better just because it is more expensive / external. Also, raw bitrates (YV12/SD) ain't so big that any modern harddrive would be a bottleneck. But yeah, CPU shouldn't be a bottleneck either when using huffyuv. Last edited by juhok; 9th June 2009 at 18:12. |

So is there any specific usb device one can recommend? I am mainly going to use it to record gameplay video from my consoles and handheld systems.

Have a look for FireWire, it should be there too

The best format for capturing if you have such hardware resources would be HuffYuv (lossless) then DV and/or M-JPEG (generously set). Quote:

For "digital" sources you don't need a TBC since the signal is clean and well formed (the analog video is output from RAM using a stable quartz PLL). You may need a TBC for tape systems (VHS, etc.). Hand held devices have generally a lower resolution (it's scaled up to the TV standard, be it NTSC or PAL) so any cheap USB card would probably be a good choice. As for game consoles, it depends on their resolution. Yes, ADVC-300 is an overkill, unless you plan VHS too. Its younger brothers -55 and -50 are simply Ok. ------- And of course, it depends on what do you intend to do with the capture afterwards - don't bother to buy an AVID system for capturing video from your handheld for youtube (which has VCD like resolution).

Sorry, but im confused, a lot of those terms went over my head.

I could also use a USB drive, which is sadly faster than the internal drive. Quote:
Besides, some of my game systems are designed to output to HD and I sadly don't have a HDTV.... or HD capture device, the games look bad enough on SD, I don't want to make them look worse with a crappy capture device. Quote:
What is TBD? What is a PLL? I know that quartz crystals are usually used for timing though... And what is ADVC-300? I didn't understand much of tht last paragraph.

2. once DV you don't need to bother with Huffyuv or M-JPEG, it's DV (there are 5 or more codecs available, one free in Windows). 3. if an USB HDD is faster than your internal HDD, which I said before but you didn't listen, than you cannot capture RAW on your HDD, possibly also not on your USB HDD. 4. capturing HD is not only a matter of resizing, but a matter of compatibility. You need an HD card which is expensive... 5. for the last paragraph (TBC etc.) you need to read, google.com is your friend, or maybe some stickies under Capture -> http://forum.doom9.org/forumdisplay.php?f=10. Read all the posts concerning Video capture, there are not so many anyway ... 6. If you don't know what ADVC-300 is, then I'm afraid you haven't read the replies (posts 2, 3 and 5)), which is sad ...

Except I said that 1. I am looking for a SD capture device and 2. I said that used to be looking for a HD capture device that worked with Component, an ANALOG source. 3. I said I had recorded RAW video from a NTSC source before. Quote:
I also find it rather annoying that you quiz me on "not listening" when I made it very clear that I am looking for a SD capture device that works over analog video and you assumed I am looking for a HD device that captures digital video. Quote:

2. Half the links in the stickies, INCLUDING the one that says what TBC is, are broken. 3. You realize just typing random 3-letter anronyms into Google would give me millions of random results right?

You are SERIOUSLY going to try to start an "Europeans are better than Americans" argument? Why are you bringing personal (And somewhat stereotypical) racial debates into a topic about capturing video? Quote:

I said since I cannot capture in HD using component, I will have to settle for capturing in SD with composite for now. Seems you completely misunderstood what I was asking and just instantly assumed I didn't know anything. I don't know why you suddenly chose to pick a fight with me for no reason, I just posted here asking for help, and then you suddenly went off being egotistical, telling me off, insulting me, and didn't even understand what I was posting in the first place. On top of this you made racist remarks about Americans, Chinese, and Indians.

I thought you want a good capture card (you asked however for an USB one) but I assumed that you prefere quality over connectivity. Unless you capture once and use it as it is, it is against common practice to capture directly xVid or h.264. If you "work" your video, these codecs will generate artefacts making the best capture card output look like a cellphone video. DV use intraframe compression, is therefore easily cut (framewise) with no noticeable generation loss. xVid, h.264 and MPEGs use GOPs. Of course you can recode the output into a distribution format (MPEG, divx, h.264 etc.). H.264 is not as supported by the hardware as you may think (there are numerous limitations to coding parameters, like QPEL for Divx). If you took you time reading the sticky -> http://forum.doom9.org/showthread.php?t=78797 (first link, point 5.3 -> http://www.doom9.org/capture/sizes_advanced.html), then you'd already found the perfect chip for your needs and pick the card using it. The market is changing and diverse, some products are available only in a given region or may bear different names. Quote:

It seems there is some confusion.
None of my systems can handle a HD capture right now, the only one that is powerful enough is one of my laptops, and since they only come in PCI-E, there is no way I can install one on it. Just forget I mentioned HD for now, I know that USB is not enough bandwidth and I do not have a single system that can take a PCI-E card, unless you know of a standalone box that can do it. (e.g., a device that lets me record straight to an internal harddrive, no computer connection needed, then be able to copy that file it recorded to my computer for encoding/editing) Because of this, for now, I am just planning to capture SD video through composite cables, using a device that is connected by USB (so I can use it on my laptop). I will worry about capturing HD video once I can afford to build a new system, I need a new desktop to replace this aging Pentium 3 system anyway. I am NOT planning to capture into Xvid or h264. I am planning to capture into either RAW or with the Huffyuv codec to prevent overloading the CPU and framedrops while capturing. AFTER the capture has been finished and saved as a RAW or Huffyuv file, I will then re-encode it using wither xvid or h264.

HuffYuv, according to its developer, needs only 600 (or 800) MHz for a Full PAL capture. It compresses about 50%. It's highly recommended, although one has to stay in the color space of YUV till the final encoding. RAW is not needed, because you'll end with a file so large (Huffyuv is also large) that most of your software will not handle it [properly]. Also capturing RAW will overload the internal busses leading to dropped frames on poor designed mainboards and/or periferics or on weak PCs. Converting the RAW into Huff you'll partially free at least one bus. The new PCs may not have such "symptoms". However, depending on your taste for quality, at least in Europe, there is no good card under 200€. The good ones usually come with a PCI[-x] card plus an external break-box. As I've said earlier, most USB cards capture at low resolution then scale it to the desired one, due to bandwidth limitations (or cheap design). In Germany you have the right to bring back the product within 2 weeks (4 weeks for online), no questions asked. You may find one such shop also in US (I assume there are such shops) and have a try on several with the procedure described in the sticky (or in its reference links, or google after it). |

Argh, I haven't responded to this in a while, sorry about that.
Yes I know, the entire point of this topic was that I made it so people can recommend for me a good USB capture device.

Actually, are there any that can also do 480p through component?

its not usb, but check http://www.matrox.com/video/en/products/mxo2_mini/ (from my experience capture cards are still pain in the ass, the pro versions as well, so you may actually spare some (lots of) time by investing a little higher...)
